Bedeguar

Bedeguar (Persian and Arabic bādāwar, literally 'wind-brought;,' sometimes explained as made up of Persian bād, 'wind,' and Arabic ward, 'rose'), a remarkable Gall (q.v.) of roundish shape, but covered with shaggy branched processes, like those familiar in the moss-rose, often found on the branches of various species of rose, particularly of the sweet-brier, upon which account it is sometimes called sweet-brier sponge. Although of course sharing the astringent properties of galls in general, it has long ceased to be of any medicinal repute.
